Step-by-step explanation:

f (g (x))= f (x^2+7) = 2 (x^2+7)+1 = 2x^2+14+1

= 2x^2+15

Step-by-step explanation:

so basically f(g(x)) is telling you to plug the entire g(x) equation into x in the f(x) equation so it will look like this

2(x^{2} +7x

2

+7 ) + 1

and then simplify

2x^{2} +14 + 12x

2

+14+1

2x^{2} +152x

2

+15
